Bertelsen & Scheving is among the leading architects working with restoration and transformation of existing buildings, from the Queen's palace to old industrial constructions, transformed into innovative campus space.

Founder Jens Bertelsen have developed a practice and set of principles around the idea of appreciation: The architect should first and foremost work to appreciate what s/he is presented with all in the context of past, present and future. So the point of departure for any preservation or transformation project is the original architect's foundational idea for a structure. From there on the work approaches questions such as the expected behaviour of contemporary and future users as well as the character of the structure.  

Based on this practice Bertelsen & Scheving also functions as consultancy, helping cities or owners to transform areas or building into active space for living, offices or public areas.
